“Children and people with asthma or other respiratory disease are most at risk for experiencing symptoms. Active children and adults, and people with respiratory disease, such as asthma, should limit prolonged outdoor exertion. Peak ozone levels are predicted to occur between 2 to 8 p.m. so make sure you get your activity or exercise in before or after these times to minimize health effects,” DEEP says.

The worst air will be in New Haven County into northeast Connecticut. The ozone forecast for Fairfield County is moderate.

“High pressure off the East Coast this Wednesday into Thursday will produce sunny skies and a steady southwest wind. These conditions will transport air pollution from the I-95 corridor into the state over the next two days. The clear and sunny weather will enable additional transported and homegrown air pollutants to mix in the atmosphere and form a secondary pollutant, ground-level ozone, which will also contribute to poor air quality along the I-95 corridor and into southern New England,” DEEP says.
